[net.chess] ambiguities and errors in the posted descriptive scores

uncle@ihuxa.UUCP (jfs) (12/30/84)

The posted descriptive score for Game #19 of the World Chess Championship gives
`29. R(Q)-Q2' as White's 29th move.  This is ambiguous, because before the move
White has a Rook on Q1 and a Rook on Q4, both of which can move to Q2.  I
cannot figure out the likely move, so I appeal to the net for an answer.  Which
Rook moved?

The problem with Game #19 is trivial compared to the problem with Game #28,
since after the ensuing exchange of Rooks it no longer makes a difference
which Rook moved to Q2.  The problem with Game #28 is that the posted score
for Black's 22nd move is identical to the posted score for his 23rd move.
On both occasions Black is reported to have moved `... QR-B1'.  This is
impossible.  A move is missing, and the missing move was mistakenly reported
as `... QR-B1'.  I cannot figure out the missing move, nor can I even determine
which move is missing -- whether it is the 22nd or the 23rd.  Again, I throw
the question to the net.  What were Black's 22nd and 23rd moves in Game #28?

Please reply to the net, as I am sure the topic is of general interest.
